Embodiment Construction

[0028] Such as figure 2 Shown, a kind of polyester fabric bleaching and dyeing process comprises the following steps:

[0029] 1) Add additives, add alkaline leveling agent, dispersant, scouring agent, degreasing agent, dyeing accelerator to the bath liquid after entering the cloth at room temperature;

[0030] 2) Add disperse dyes, add additives and run for 5-15 minutes before adding disperse dyes;

[0031] 3) Increase the temperature and add lye, gradually increase the temperature after adding disperse dyes, add lye when the temperature reaches 70°C, if the cloth has mold spots, add H 2 o 2 ;

[0032] 4) heating up, gradually heating up to 130°C;

[0033] 5) keep warm, keep at 130 degrees for 20-40 minutes;

[0034] 6) Wash with cooling water.

[0035] Among them, step 3) the heating rate from normal temperature to 70°C is 3°C / min, step 4) the heating rate from 70°C to 90°C is 2°C / min, and the heating rate from 90°C to 130°C is 1.3°C / min min.

Abstract

The invention discloses a scouring, bleaching and dyeing process for polyester fabric. The scouring, bleaching and dyeing process comprises the following steps: 1) addition of additives: an alkaline leveling agent, a dispersing agent, a scouring agent, an deoil agent and a dyeing accelerant are added to a bath solution after fabric feeding at the room temperature; 2) addition of a disperse dye: operation is performed for 5-15 min after addition of the additives, and then the disperse dye is added; 3) heating and addition of alkaline liquor: heating is performed gradually after the disperse dye is added, the alkaline liquor is added when the temperature reaches 70 DEG C, and H2O2 is required to be added if the fabric has mildew stains; 4) temperature increasing: the temperature is increased gradually to 130 DEG C; 5) temperature keeping: the temperature is kept at 130 DEG C for 20-40 min; 6) temperature reduction and washing. According to consideration of energy saving, emission reduction, improvement of product quality and increase of production efficiency, the polyester home fabric is dyed with a disperse dye alkaline bath, the process procedure can be shortened, energy saving and emission reduction can be realized, further, problems caused by spinning oil, a sizing agent and oligomers can be solved, and the product quality can be improved.

Description

technical field [0001] The invention relates to textile printing and dyeing technology, in particular to a polyester home textile fabric dyeing process. Background technique [0002] With the popularization of high-speed yarn technology, chemical fiber factories must use high-speed spinning oil to oil the filaments in the process of polyester spinning in order to increase production capacity and ensure quality, so as to increase smoothness during spinning and Reduce the friction between the tow and the silk path during the production process; ②Increase the clustering; ③Enhance the antistatic property and other important functions, but the spinning oil must be removed by alkali and surfactant during the printing and dyeing of polyester fabrics . In addition, polyester fabric products are often subjected to appropriate alkali weight reduction pre-treatment due to style requirements. In order to meet the subsequent acidic condition dyeing, such as figure 1 As shown, the trad...
